This is an old faro case keep.It was made by A.H. Harrison, Co. This Seattle business was operating from 1892-1908. They sold a lot of gambling equipment to folks on the way to the Alaska gold fields. This hinged piece is made of heavy wood with ivory counters. Closed dimensions are 6.5 inches x 13 inches x 2.5 inches. Opened, it is 13 inches x 13 inches x 1.25 inches. My question is: I'm planning on selling this on eBay. What do you think I should expect to get?
